AeroDynic gear imbalance

Everbody knows the terrible sound of "dancing" rotators in older Aerodynic with gear wheels.

I guess the gap (red arrow) is the issue.
And the idea to fix it is a washer. But the problem is to disassemble the unit.
What about a C-washer to fill the gap and hold it in position.
Anybody other solutions for this widespread problem?

This issue is caused by uneven wear of the plastic gear due to lack of lubrication.

I would view the washer fix as a stop gap, and a permanent fix to just replace the rotator with a non wobbly one.

Many have found that applying grease to the shaft helps aleviate the problem. The grease tends to fill the voids causing the sloppiness.
